A way back, someone asked about primary vessles. Jack had written that his wife made some neat little elastic banded muslin "caps" for his primaries. I had my girlfriend do the same for me, and the little "chef hats" are excellent.
We decided to take this a step further and make little cloaks for my secondaries. I need something like this because my basement is too cold to complete fermentation in the winter, and the kitchen collects the carboys, so there is too much light around for a truly dark wine. I haven't dyed these dark color yet, but will very soon.
Here is an example that I have on a batch of blueberry that is still pushing the airlock every couple seconds.
In the background there are several batches of Welch's products going that I really don't care about the color much...
